DC/DC CONVERTER CONTROL DEVICE AND CONTROL METHOD FOR HIGH SPEED BATTERY CHARGER USING DSP

摘要

A DC/DC converter control device and a control method for a high speed battery charger using a DSP(Digital Signal Processor) are provided to easily change a dead time required for a ZVC(Zero Voltage Switching) technique. A DC/DC converter control device for a high speed battery charger using a DSP includes a DC/DC converter(11) therein. The DC/DC converter control device further includes an A-D convert module(12-15) and a DSP. A phase shift PWM(Pulse Width Modulation) signal is outputted to drive the A-D convert module constituting the DC/DC converter. The DSP outputs the phase shift PWM signals by interleaving the phase shift PWM signal when two DC/DC converters are to be used in parallel.
